Breakdown Information
The following list contains a number of common problems that may arise dur‐
ing work, together with the ways to solve them.
Code
Type
Fault
Likely cause
Solution
E2011
Warning 1 Low pressure
The circuit pressure is below 0,5 bar (in Drive side) Pressurise the circuit
to 1,5 bar
E2012
Warning 2 The machine does
not start
Pump CP‑1 does not start in the speed check mode Make sure the system
is in a "AF" status be‐
fore enabling
E2013
Warning 3 The machine does
not maintain the set
point temperature
The 3MV‑1 3‑way mixing valve may have a me‐
chanical fault or the electrical connection cable may
be broken
The level of thermal output to be dissipated is high‐
er than the machine’s rated thermal input
Check the 3MV‑1 mix‐
ing valve Reduce the
thermal output
E2014
Warning 4 Outlet fluid tempera‐
ture too high
The fluid temperature at the outlet is higher than the
set point temperature (T_set) plus a ΔT defined by
parameter P‑0‑1380 for a given time, defined by pa‐
rameter P‑0‑1381 (see IndraDrive programming)
If necessary, change
the P‑0‑1380 and/or
P‑0‑1381 parameters
F2011
Error 1
Low pressure alarm The circuit pressure is below 0,2 bar (in Drive side) Pressurise the circuit
to 1,5 bar
F2012
Error 2
High temperature
alarm
The fluid temperature (in the Drive side) is above
the maximum allowed temperature limit (see pa‐
rameter P‑0‑1382)
If necessary, change
the P‑0‑1382 parame‐
ter
